First, if I lived up north, I would have a second set of steel rims with quality winter tires mounted on them. If I was merely visiting in bad weather, I would have tire cables in the vehicle. These cables are a modern replacement for chains.
Second, I would only drive in bad weather when absolutely necessary.
Third, whenever I make trips up north, I make sure my car is stocked with emergency supplies, like a flashlight, sand or cheap kitty liter, a shovel, an ice scraper, blankets, etc.
Lastly, whenever I drive on snow and ice (which isn’t often), I take things nice and slow, and plan stops and turns far in advance. Many northern drivers don’t like it, and ridicule my slow moving vehicle with Florida plates, but I ignore it. They can drive their cars the way they like, and I shall drive my car the way I like.
